Note that there is a time delay while your gravatar image propagates throughout the internet. If you are experiencing problems then go to the gravatar site http://en.gravatar.com/ and read the FAQs as it contains common questions and answers to them http://en.gravatar.com/site/faq/

One other thing is to log out, clear your browser cache and cookies, restart your browser and then try again. Some browsers hang onto gravatars and blavatars and won't update them till you clear everything out.

We need specific information please.
What is the URL for the blog to which you are referring starting with http://
Exactly where do you expect to see the Gravatar to appear on your blog that it's not appearing now?

Sometimes new member think their gravatars are supposed to automatically appear in every post they publish in their own blog- this is NOT the case.

On your own blog your grravatar will appear only next to your comments and only if you have set that up here > Settings > Discussion Likewise it will appear only on blogs that are gravatar equipped and have their Discussion settings set up to enable gravatar display.

Is the lack of display next to your comments what you are referring to or not?
